Interrelation of a Z(3) Gauge Theory on the Flat Lattices and a Spin-1 BEG Model
N. S. Ananikian, R. R. Shcherbakov
Abstract
The Z(3) gauge model with double plaquette representation of the action on the flat triangular and square lattices is constructed. It is reduced to the spin-1 Blume-Emery-Griffiths (BEG) model. An Ising-type critical line of a second-order phase transition is found.
